Narrative:

As first officer, I was flying toward lga about 25 NM east of cleveland when the ECAM indicated we had an avionics system fault. This was followed quickly by a vent extract fault and shortly thereafter an 'avionics smoke' indication. We asked ZOB for a turn toward cleveland, a descent, and told them our problem. We declared an emergency and landed in cleveland without incident. We had the fire truck follow us to the gate, checked the aircraft over carefully, and found no fire, smoke or fumes. Suspect an indication problem.
